Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic urinal cleaning device for automatically cleaning a urinal.

[0002]

[Prior art]

 In recent years, hygiene awareness has risen along with the improvement of people's living standards, and flush toilets have spread. However, there were many people who did not flush water into the urinals in toilets such as department stores where an unspecified number of people came and went, which caused a sanitary problem. Therefore, an automatic urinal cleaning device that automatically senses the human body and flows water into the urinal has become popular. The conventional automatic urinal cleaning device will be described below. FIG. 6 is an explanatory view showing a method of attaching a conventional automatic urinal cleaning device to a flush valve.

As shown in FIG. 6, in a conventional automatic urinal cleaning device 70, a battery 72 is attached to one end of a main body 71, and a drive unit 73 and a sensor unit 74 are fixed to the other end. A drive lever 75 driven by a drive unit 73 is provided, and a chassis 76 is fixed to the central portion. The chassis 76 is provided with a body mounting screw hole 77 that is bored, and a holding metal fitting 79 that is fixed to the body mounting screw hole 77 using a body mounting screw 78 is provided. Further, the holding metal fitting 79 is provided with a fixing screw 80. Reference numeral 81 is a flash bulb, and 82 is a push button. Further, the conventional automatic urinal cleaning device 70 includes a cover (not shown). Regarding the conventional automatic urinal cleaning device 70 configured as described above, a method of attaching the automatic urinal cleaning device 70 to the flush valve 81 will be described below. First, a holding metal fitting 79 is provided on the upper end of the flash bulb 81, and the holding metal fitting 79 is fixed to the flash bulb 81 using a fixing screw 80. Then, the chassis 76 is covered with the holding metal fitting 79, and the two body mounting screws 78 are tightened to be mounted, and finally the cover (not shown) is covered.

[0004]

[Problems to be solved by the device]

 However, in order to mount the conventional automatic urinal cleaning device 70 on the flush valve 81, the fixing screw 80 provided on the holding metal fitting 79 is screwed in to fix the holding metal fitting 79 to the flash valve 81, and the holding metal fitting 79 is attached to the chassis. It is necessary to cover with 76 and tighten the two main body mounting screws 78 to attach them, which is very troublesome and time consuming. The present invention has been made in view of such circumstances, and an object thereof is to provide an automatic urinal cleaning device that can be easily attached to a flush valve without requiring labor and time.

[0005]

[Means for Solving the Problems]

 The automatic urinal cleaning device according to claim 1, wherein the flush valve is mounted by being driven by a human body detection sensor, a motor driven in response to the human body detection sensor, and a cam rotated by the motor. An automatic urinal cleaning device comprising: a drive lever that pushes a push button; a base for fixing these; and a fixing means for fixing the base to the flush valve, wherein the fixing means is attached to the base. It has a ring that is attached and fits in the upper part of the flash bulb, and a fixing screw that is screwed into the ring from the outside.

[0006]

[Action]

 The automatic urinal cleaning device according to claim 1, wherein a ring provided on the base is fitted into an upper portion of the flash valve, and a fixing screw is screwed into the ring from the outside to make the automatic urinal cleaning device a flush valve. It can be installed in a short time without any trouble.

【Example】

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. 1 is a perspective view showing a state where an automatic urinal cleaning device according to an embodiment of the present invention is attached to a flash valve, FIG. 2 is a plan view of a ring provided in the automatic urinal cleaning device, and FIG. FIG. 4 is a side view of the same, FIG. 4 is an explanatory view showing a method of attaching the automatic urinal cleaning device to a flush valve, and FIG. 5 is a front view of a cover put on the automatic urinal cleaning device. As shown in FIG. 1, an automatic urinal cleaning device 10 according to an embodiment of the present invention has a base 11 and a human body detection sensor 12 using an optical sensor fixed to one end of the base 11. A motor 13 is fixed to the end, and a ring 15 made of an aluminum alloy material is provided in the center through a chassis 14. The base 11 is fixed to the outer frame 16. On the lower surface of the chassis 14, five mounting screws 18 are screwed into mounting screw holes 17 (see FIG. 2) to fix the ring 15. As shown in FIGS. 2 and 3, the ring 15 has a fixing screw hole 19 formed in its side surface, and a fixing screw 20 (see FIG. 1) is screwed into the fixing screw hole 19. A rotary cam 21, which is an example of a cam, is attached to the tip of the motor 13.

A drive lever 23 is provided on the base 11 via a fixing pin 22, one end of which is in contact with the rotary cam 21 and the other end of which is provided with a pressing portion 24. In addition, 25 is a battery unit, 26 is a flash valve, 27 is a push button, and 28 shown in FIG. 5 is a cover. Next, a method of attaching the automatic urinal cleaning device 10 according to the embodiment of the present invention to the flush valve 26 will be described. As shown in FIG. 4, the fixing screw 20 is loosened, the ring 15 is fitted into the upper portion of the flash valve 26, and the pressing portion 24 is brought into contact with the push button 27. Then, the fixing screw 20 is screwed into the attachment screw hole 17 (see FIG. 2) to fix the upper portion of the flash valve 26, the automatic urinal cleaning device 10 is attached, and finally, the cover 28 shown in FIG. It can be fixed to 16 and can be installed in a short time without any trouble. Although the ring 15 is made of an aluminum alloy material, other metal materials or synthetic resin materials may be used. The human body sensor 12 is an optical sensor, but other sensors such as ultrasonic waves may be used.
